Abstract
A heat roller of an image forming apparatus is capable of preventing a terminal from being broken and improving contact performance of the terminal. The heat roller includes a heat transfer pipe, a heat generating body disposed at the heat transfer pipe and generating heat, a terminal to apply power to the heat generating body, and an end cap connected to the heat transfer pipe, and having a groove such that the terminal is smoothly inserted without forced bending.
